AHRANGEMENT IN WATER CLOSETS Filed March 8, 1928 Patented Dec. 17, 1929 UNET STATES FATENT @Erll JOHN WALDEMAR -IENREKSON, F STOCKHOLM, SWEDEN ARRANGEMENT IN WATER-CLOSETS Application led March 8, 1928, Serial No.

This invention relates to an arrangement in water closets with automatic flushing.

Tn the accompanying drawings a couple of embodiments of the invention are shown. Fig. 1 is a vertical section through the closet to which the invention is adapted. Fig. 2 is a detailed section through a somewhat altered embodiment according to the invention.

Tn the shown water closet to which the inl@ vention is adapted, the ringor oval shaped upper edge of the closet bowl 1 is surrounded by a lushing water chamber 2 in the closet itself, the inner wall o't` which flushing water chamber' Q is formed by a movable closing ring 3, of the same form as the upper edge of the closet bowl. The ring 3 rests on helical springs t, arranged in sleeves 5, which springs normally hold the ring in the position shown in F ig. 1, whereby there is a ring 2o shaped outlet canal G trom' the flushing water chamber. On the lower edge of the ring 3, there is arranged a packing ring 7, which, when the seat 8 is pressed down, tightens against the upper part of the closet bowl, so that thc flushing water chamber is closed from the bowl 1. The flushing water can be conveyed to the flushing water chamber through a flushing valve, float valve or the like. ln the shown embodiment there is for 30 that purpose a flushing valve 10 ot' already known construction controlling an inlet 9. This flushing valve 1() is connected in a known way with the ring 3 so that by the pressing down of the ring by the seat, the valve is actuated and lets the water flow into the flushing chamber Q. l/hen the pressure on'the seat ceases, the ring 3 is moved upwards by the springs il, so that the flushing water flows through the outlet canal G down into the closet bowl.

ln order that one shall now be able to manually actuate the flushing valve without pressing downthe seat, which is preferable in certain cases, the following arrangement accordingto the invention is made in the embodiment shown in Fig. 1. In the flushing valve 10 is arranged a lever 11, which is swingable at its one end v12 and which is joined with the valve lever in such a way that this, when the lever 11 is swung, is moved 260,076, and in Sweden March 24, 192'?.

upwards, whereby the flushing valve is opened, or is moved downwards, whereby the flushing valve is closed. The other end oi the lever 11 is connected with one end of chain 13 or the like, the other end of which is tastened on the under side of the seat. When the seat 8 is swung upwards in substantially vertical position, the flushing valve 10 is opened, on account of the chain connection 13, and lets the water into the flushing water chamber, wherefrom the water flows through the open canal 6 down into the closet bowl. The flushing water flows in through the flush ing valve, as long as the seat against the action ot a spring actuated piston 111, arranged in a cylinder' 15, is held in its upwards swung, substantially vertical position. As soon as one releases the seat, the spring actuated piston 14e moves the same downwards, and the liushing valve stops letting the lushing water into the chamber 2. Thus one need not fear that the Hushing water, through ones forgetting to lower the seat, will continue to flow into the flushing water chamber, after one has left the closet.

Tn the embodiment shown in Fig. 2 one end ott the chain 13 is not fastened to the seat, but in the one arm of a two armed lever 16, which is swingable round a pin 17 and the other arm of which, is connected with the piston 1l. The connection between the piston and the arm ot said lever is suitably made in such a way, that the end ot the arm of the lever is made fork shaped, so that it can grip a side tap on the piston 14. lllhen the seat 8 at the upward movement has come into substantially vertical position, it actuates the piston 14, so that this is shoved inwards into the cylinder 15 against the action of its spring. Thereby the lever 16 is swung in such a way that a pulling of the chain takes place, and the flushing valve is opened. As soon as one releases the seat, the piston 14 is shoved outwards by its spring, and the flushing valve is closed.

The shown and described embodiments can of course be modified in several respects, without deviating from the important character istics of the invention.

Having now described my invention, what l claim is new and desire to secure by Letters Patent is l. ln an automatic flushing water closet, having a hinged seat, a bowl, a liushing chamber directly in communication therewith, means for supplying water to said chamber, a valve for controlling the ilow of water from the supply means, means actuated by the movement of the seat to lowered position to positively etiiect opening` ot the valve, other means actuated by the movement of the seat to raised position to also positively effect opening ot the valve, both of said means being inactive in an intermediate position of the seat, and means yieldably supporting the seat in the said intermediate position.

2. ln an automatic flushing water closet, having a hinged seat, a bowl, a flushing chamber directly in communication therewith, means for supplying water to said chamber, a valve for controlling the tlew of water from the supply means, means actuated by the movement of the seat to lowered position to positively effect opening of the valve, other means actuated by the movement of the seat to raised position to also positively effect opening of the valve, both ot said means being inactive in an intermediate position of the seat, and means yieldably supporting the seat in the said intermediate position, the said means comprising a closing ring yieldablv supported in the open top of the bowl and constituting a support for the seat in the said intermediate position thereof.

3. ln an automatic flushing water closet, having a hinged sea-t, a bowl, a flushing chamber directly in communication therewith, means for supplying water to said chamber, a valve for controlling the iow of water from the supply means, means actuated by the movement of the seat to lowered position to positively eiect opening ot the valve, other means actuated by the movement ot' the seat to raised position to also positively eiect opening ot the valve, both of said means being inactive in an intermediate position of the seat, and means yieldably supporting the seat in the said intermediate position, the said means comprising a closing ring yieldably supported in the open top ot' the bowl and constituting a support for the seat in the said intermediate position thereof, the said ring also constituting means :tor closing communication between the bowl and the flushing chamber when the seat is in its lowered position.

lin wit-ness whereof, I have hereunto signed my name.
